The 'Boyfriend' star's manager also reassured fans by promising that the cancellation of Justin's Portugal show this week wasn't due to low ticket sales, but due to the practicality of moving the show from one location to another.

"It has nothing to do with anything other than that," Scooter promised. "Tell everyone Justin is good, really good."

Justin Bieber has now taken his 'Believe' tour over to Europe, but was forced to cancel one of two shows in Lisbon, Portugal this week due to "unforeseen circumstances".
